Hi,
I have an 'uploader' function in my app that can populate the CloudKit private database with a lot of user data. I batch the records into multiple CKModifyRecordsOperations, across the different record types, before I upload them. When I do this with a lot of data, I sometimes get CKErrorRequestRateLimited errors, with a value for CKErrorRetryAfterKey specified in the CKError, for a few of the modify operations. I usually respond by creating new operations for the same records, delaying them by the specified CKErrorRetryAfterKey key, and then retrying the operations. But those operations end up getting more errors with CKErrorServiceUnavailable or CKErrorRequestRateLimited again.
So my question is .... is the CKErrorRetryAfterKey value supposed to be cumulative, and does it apply across operations? For e.g. if I have Operations 1, 2 and 3, and each of them returns with a 'retry' error value (say 5, 10, and 15 seconds) ... can I retry them with the retry values for each operation (5 secs for Op1 etc), or should I choose the highest retry value before trying another operation (15 secs), or should I add them up and not try anything for the sum of their retry values (30 secs)? And is this ‘retry’ value limited to each record type, or is it generally for the whole container?
If anyone has an insight into this, I would love to know.
Thanks,
Zulfi Shah.
